Which of the following metabolic pathways generates a proton gradient?
A)the oxidation of pyruvate to acetyl CoA
B)the citric acid cycle
C)chemiosmosis
D)the electron transport chain
E)glycolysis

Question

Quizplus · Accepted Answer

The electron transport chain generates a proton gradient by pumping H+ ions across the inner mitochondrial membrane, creating a concentration gradient that is used to generate ATP through chemiosmosis. The other listed metabolic pathways do not directly generate a proton gradient.
